        Applications of nuclear magnetic resonance to determine the structure and interactions of ligands, peptides and enzymes 

        Monasterio Opazo, Octavio; Nowak, Thomas (1996)
        Nuclear magnetic resonance (NMR) spectroscopy is emerging as a powerful tool for the study of enzyme structure and function. This article discusses the general principles of NMR and the potential information this technique ...

        Nuclear magnetic relaxation for the spin-degenerate Anderson model 

        Universidade Estadual Paulista (Unesp); Universidade de São Paulo (USP) (Elsevier B.V., 1991-05-01)
        A renormalization-group calculation of the temperature-dependent nuclear spin relaxation rate for a magnetic impurity in a metallic host is reported. The calculation follows a simplified procedure, which produces accurate ...

        On the Validity of the Relationship 1/T = 1/T B+1/T S+1/T D in NMR Techniques With Regards to Permeability Estimation of Natural Porous Media 

        Unknown author (Frontiers, 2021)
        One of the most relevant feature of geophysical techniques based on nuclear magnetic resonance is their ability to estimate the permeability of natural porous media, since other geophysical techniques, as the use of the ...

        Rate constants determined by nuclear magnetic resonance 

        Monasterio Opazo, Octavio (Academic Press, 2001)
        Fast kinetic methods are used to measure reactions that take place in less time than required to mix the reagents manually and to measure the reaction by usual methods, like UV-visible spectrophotometry and fluorescence. ...

        Molecular relaxations in polyfluorene based cast films 

        Faria, Gregorio Couto; Cossiello, Rafael F.; Atvars, Teresa D. Z.; Azevêdo, Eduardo Ribeiro de (ElsevierLausanne, 2009-11)
        This article reports a study of the thermal relaxation in cast films of two polyfluorene based polymers, poly{9,9-dioctylfluorenyl-2,7-diyl} (BE329) and poly{(9,9-dioctyl-2,7-divinylene-fluorenylene)-alt-co-[2-methoxy-5- ...

        Molecular relaxations in polyfluorene based cast films 

        Faria, GC; Cossiello, RF; Atvars, TDZ; deAzevedo, ER (Elsevier Science SaLausanneSuíça, 2009)

        Magnetic resonance study of the crystallization behavior of InF3-based glasses doped with Cu2+, Mn2+ and Gd3+ 

        Universidade de São Paulo (USP); Universidade Estadual Paulista (Unesp) (2006-09-15)
        The crystallization of fluoroindate glasses doped with Gd3+, Mn2+ and Cu2+ heat treated at different temperatures, ranging from the glass transition temperature (Tg) to the crystallization temperature (Tc), are investigated ...

        Measuring the solubility product constant of paramagnetic cations using time-domain nuclear magnetic resonance relaxometry 

        Universidade de São Paulo (USP); Universidade Federal do Espírito Santo (UFES); Universidade Estadual Paulista (Unesp); Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA) (Elsevier B.V., 2015-07-01)
        The use of time-domain NMR relaxometry is already well established for determining the concentration of paramagnetic cations. Paramagnetic cations have unpaired electrons, and in aqueous solutions, they interact with ...

        NMR relaxation studies of slow motions of HDA hydrocarbons chains inside lamellar structures 

        Lopes, L. V. S.; Schneider, J.; Magon, Claudio José; Donoso, José Pedro; Lozano, Harold; González Moraga, Guillermo (TAYLOR & FRANCIS, 2006)
        Measurements of H-1 and C-13 Nuclear Magnetic Resonance (NMR) for the nanocomposite materials formed by the intercalation of hexadecylamine (HAD) in metal oxides (TiO2, V2O5, CrO3 and MoO3), are reported. The H-1 NMR ...

        Nuclear Magnetic Resonance Relaxation Studies in Shale 

        Ramia, Maximo Elias; Martín, C. A. (Springer Wien, 2016-10)
        The present work involves a comprehensive experimental study of proton (1 H) nuclear magnetic resonance (NMR) transversal relaxation in shale. The sample studied belongs to the “Vaca Muerta” formation of the Neuquén basin, ...
